WEB-HOLDER MECHANISM FOR KNITTING-MACHINES.

Specification of Letters Patent. Patentqgfl Jan, 25 11916 Application filed July 24!, 1914. Serial No. 852,894.

To all whom it may concern:

Be it known that ][,-Ronn1rr W. Soon, a citizen of the United States, and resident of Boston, in the county of Suffolk and State of Massachusetts, have invented certain new anduseful Improvements in lVeb-Holder Mechanism for Knitting-Machines, of which the following is a specification.

My invention relates to devices for positioning independently movable web-holders with respect to the needles and needle carrier of a knitting machine.

In the accompanying drawings, Figure 1 is a vertical section through the needle carrier of a knitting machine showing the device in position; Fig. 2 is a perspective of the hold-down ring.

' As shown in Letters Patent to George D. Mayo No. 726,178 dated April 21, 1903, upon which my device is an improvement, needle carriers for knitting machines such as the cylinder 1 are employed in connection with an attached web-holder bed 112 carrying radially sliding web-holders 105 for actuation by a cam-ring Ill, the vertical position of said web-holders being determined by engagement of one of their parts with a slotted attachment of the needle cylinder 1, said web-holders being held from rising by an internal collar or ring having an integral annulus taking between arms of the webholder. I provide instead of this structure a guide-ring 297 held by screws 3 and cleats 2 taking into a groove 13 at the upper end of the needle cylinder l. thus permitting rotative adjustment and clamping of said'ring 297 when desired, said ring overhanging the inner surface of said cylinder at l, and being provided with milled slots of the proper gage and frequency toreceive and guide the webholders 105, whose lower surfaces rest on the surface 6 at their proper height in relation to web-holder bed 112 and the needles. The said slots are free-ended, and to prevent web-holders in an inner position from rising with advancing needles,

' I provide a hold-down ring 10 resting freely 12, the short projections 12 interlocking with the under surface i of the guide-ring 297. The parts may be assembed by springing the feet 12 inward. Lint moving with the webholders can not find lodgment against the thin outer surface of the ring 10, while the openings between the feet 11 permit lint and other detritus pushed from the grooves 5 to fall within the cylinder 1. The construction of the ring 297, by the use of the ring 10, is much simplified and cheapened, while the ends of the grooves in the guide ring and the top of the hold-down ring are exposed for cleaning without dismantling the machine. I

\Vhat I claim is:

1. In a web-holder device for knitting machines, the combination with web-holders of 'a grooved guide-ring to position the webfor movable web-holders held on said cylinin the said cylinder.

In testimony whereof, I have signed my name to this specification in the presence of two subscribing witnesses.
